Abstract (en)
[origin: WO2021006855A1] An engine with a slider-crank mechanism, comprising a housing (1), containing a shaft (2) with a crank (3), and at least two cylinders (4, 5) with pistons (6) mounted on rods (7), the ends of which extend from the pistons (6) through guide bushings (8) of the cylinders (4, 5) and are connected to one another by means of a yoke assembly. A housing (11) of the yoke assembly is configured in the form of a frame having a rectangular cross-section and inner guiding surfaces (12) for a block slider (13) mounted with freedom of movement between said surfaces and with freedom of rotation on the crank (3) of the shaft (2). The block slider (13) is comprised of two connected halves with grooves (14) for lubricating an outer sliding surface (15). The housing (11) of the yoke assembly is mounted such that its lateral surfaces (16), provided with lubricating grooves (17), are disposed between guiding surfaces (18) inside the engine housing (1) and such as to have freedom of movement along the axis of the cylinders (4, 5) with pistons (6), and the lubricating grooves (14) on the block slider (13) do not extend beyond the outer sliding surface (15) in the frame of the yoke assembly.
